Abstract
A voltage source converter for high power application containing a plurality of valves, each valve containing a plurality of extinguishable semiconducting elements, and a valve control unit containing a computer and a pulse-width modulator providing an executing control signal for controlling the semiconducting elements. The valve control unit includes a first control containing a first pulse-width modulator for providing a first pulse-width modulation signal, a second control containing a second pulse-width modulator for providing, a second pulse-width modulation signal, a mode detector, and a selector connected to the first and second pulse-width modulator for selecting in dependence of the mode detector the executing pulse-width modulation signal.
